H. unilaterale, Willd. Rare and local. Steep banks of a stream near head 
of Paterson’s Inlet. 
. minimum, A. Rich. On rocks, trunks of trees, etc., near the sea, not 
unfrequent. Fronds with from two to six pairs of lobes. 
Common on mossy banks, in damp situations, and in 
forests. a. Fronds rigid, decurved. b. Fronds slender, flat, sometimes 
nearly 1’ in length. 
. multifidum, Swartz. Common throughout the island, ascends to fully 
2,000 feet.

Inlet. Fine pendulous fronds measured nearly thirty inches in length. 
dilatatum, Swartz. Common throughout the island at low levels. 
. javanicum, Spr. A solitary specimen of this species was collected on 
Ulva. 
polyanthos, Sw., var. sanguinolentum. Most abundant, and exhibiting 
a wide range of variation in the shape of the fronds, caused by the 
unequal development of the pinne. Occasionally the lateral pinnæ are 
less than half an inch in length, while the apical portion of the frond is 
greatly elongated, sometimes being over a foot in length. Again, the 
lateral pinne alone are elongated so’as to form a broadly flabellate 
frond. A diminutive form with fronds less than half an inch in length 
is found on the mountains. 
villosum, Col. Mount Anglem, 3,000 feet. 
. demissum, Sw. Abundant below 1,800 feet.

locality. For my knowledge of these habitats I am indebted to Mr. 
Walker. 
T. lyallii, Hook. On inclined trunks of Metrosideros lucida, Mount Anglem,
